wiki "History diff" CSS change

[dpatton]

As someone who is partially colorblind, I find that the use of RED to highlight changed text on the wiki's "History diff" makes the wiki hard to use effectively, especially when there are small changes (e.g. adding/deleting a single letter, space, or punctuation mark).

The existing wiki CSS is in /skins/common/diff.css ​http://wiki.osgeo.org/skins/common/diff.css and the relevant class is: .diffchange {

color: red; font-weight: bold; text-decoration: none;

}

My suggested changes are to replace the diffchange class with two specifications, to use different attributes for the deleted and inserted text, both being BLUE, and with deleted text highlighted with a strike-through: del.diffchange {

color: blue; font-weight: bold; text-decoration: line-through;

} ins.diffchange {

color: blue; font-weight: bold; text-decoration: none;

}

If you want to test this to see what it looks like, it's easy to do using the Stylish extension for Firefox:

• install Stylish ​https://addons.mozilla.org/en-US/firefox/addon/2108
• using Ctrl+M or the icon in the lower right corner, go into Stylish's Manage Styles
• create a style entry, using this:

---

@namespace url(​http://www.w3.org/1999/xhtml);

@-moz-document domain("wiki.osgeo.org") {

del.diffchange {

color: blue !important; font-weight: bold !important; text-decoration: line-through !important;

}

ins.diffchange {

color: blue !important; font-weight: bold !important; text-decoration: none !important;

}

}

---

• go to an OSGeo wiki page that shows a History diff: ​http://wiki.osgeo.org/index.php?title=Main_Page&diff=28053&oldid=27981
• using the popup menu from hovering over the Stylish icon in the browser's lower right corner, you can toggle the above style on/off to compare to the default wiki styling.

Martin installed and setup mediawiki ... adding him as a cc in case he might like to make this change. BTW, the configuration is now loosely described at MediaWikiConfiguration.
